i To all whom it may concerni- Be it known that T, BRUCE B. STONE, a citizen of the United States, residing at Mount Clare, in the county of l-larrisonand State of West Virginia, have invented a new and useful Acetylene-Lamp, following is a specification.)

This invention relates to acetylene generators and more particularly .to miners acetylene lam s.

An ob ect of thepresent invention to provide an acetylene gas lamp with two illdependent gas generating chambers adapted to supply acetylene gas to two independent burners.

Another object is to provide an improved valve construction for the regulation of the water supply to the gas generating chambers which will prevent any clogging of the water supply tube and will provide means whereby the latter may be readily cleaned.

With" the foregoing and other. objects in view which will appear as the description proceeds, the invention resides in the-combination and arrangement of parts and in the details ot construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein the scope of what is claimed withoutdeparting from the spirit of the invention.

In the drawings accompanying thisspecification and forming a part thereof,' the preterable form of my invention is illustrated in which Figure 1 is a acetylene lamp. Fig. 2 is a cross sectional view thereohtahen on the line A-A of Fig.

1. Fig. 3 is a view in elevation thereof. Fig. i is a sectional view taken on the line B-B of Fig. 3. v

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 is a water reservoir or tank provided with an inlet opening 2 at the top thereof. The said is provided with a cover or lid 3 opening therefor, which lid is provided with a centrally disposed air inlet opening 3 which allows the water in the tank 1 to pass readily through the openings in the bottom thereof. The cover 3 is hingedly mounted at hand is preferably provided with a spring snap of the usual construction, the same not being illustrated.

' idly sup ted below the reservoir 1 ly extending cylindrical of which the disclosed, can be made within plan view of my improved supports 5, there being two of these supports it as illustrated in Fig. 2. These supports threadedly engage as at 7, the carbid containers 6, these containers being cup-like in shape and are provided with an annular rib or shoulder 8 against which the lower endof the support 5 abuts and form a gas-tight.

juncture therewith. The upper extremity 9 of the container is spaced a distance from the bottom of the water reservoir 10 and forms therebetween what are designated as non-communicating gas chambers 20 and 21.

Located approximately central of the supports 5 are the openings 11 in the, bottom plate of the water reservoir 1 in which openings are disposed the water outlet tubes 12 which are provided with theenlarged heads. .13 which are secured within the openings 11 of the platelO, it being understood in this connection that each head 'portionl3 and the tube 12 may be forced into engagement with the side walls of the opening 11 or may be held in liquid-tight relation therewith by any suitable means.

provided with a conical valve seat having an opening 1% therein in which is adapted to fit the valve plunger or valve member 15. This member 15 is rigidly supported bya valve rod' 16 which rod extends downwardly through the tube 12 and beyond the end The head portion 13 is.

thereof. It also extends upwardly through the water reservoir 1 and terminatesin the thumb screw 1?. The thumb screw 17 extends through the-upper wall of the water reservoir 1 and threadedly engages a reinforcing boss 18 secured thereto. The upper terminal of the thumb screw 17 is provided with the outwardly flared head 19 which has a knurled face so that the latter may be readily engaged and easily turned for the adjustment of the valve 14i15, which valve it will be apparent controls the supply or" waterfront the reservoir 1 to the carbid containers 6; From the foregoing it will be ap parent that each carbid container or gas generator is provided with a separate and independent valve, and. valve actuating mechnism which thereforerenders each gas generator independent of the other.

Communicating with and extending for a slight distance within the gas chambers 20 and 21 are the gas outlet tubes 22 and 23 which it is to be noted are slit along their upper surface tor the portion thcreofwliich lies within the said gas chambers and the slit ends of these tubes are unrolled so as to be in the form. of upwardly extending 35 peculiar construction of the valves as illus- '.trated, the valve rods and valve may be troughs substantially as illustrated in Figs.- 2 an 4, the Object of these flared and mutil'ated endsbeing to prevent any of the water from spattering up therein and clogging the gas outlet tubes. The gas outlet tubes .22 and 23 communicate with the gas burners 24 and 25 respectively which are located sube stantially centrally of a disk or reflector 26 which is suitably mounted upon the reservoir 1 to which it is secured in'a rigid manner. In order to provide convenient securing means, a hook27 is illustrated as being attached to the rear portion of the lamp and .is adapted to fit within a suitable opening provided in a miners hat or may serve as a handle should it be the. desire of the user to carry the lamp.

In the practical operation of my improved lamp, a certain amount of carbid is placed within each of-the carbid containers. or cups and one of the valve rods suitably turned in order to admit water to the carbid contain ers. In this manner, gas will be generated,

and will be burned at-the burner. When'it becomes apparent that the supply of carbid in one of the containers'is about exhausted,

the other valve is opened and the-burner communicatin therewith is lighted. In this manner fioth burners may be maintained in a lighted rcondition'un'til one is completely exhausted, at which time the cup 'or carbid container may be removedwithout the disturbing of the other container and the lamp will therefore remain lighted and in a serviceable condition. By the withdrawn and the tubes 12] will thereby be maintained in an open position, it being understood in this connection that the clogging of these tubes is a serious objection to,

the usual form of carbid lamps. Further- -more by the flaring and upturning of the ends of the gas tubes, the danger of the latter becoming clogged by the spattering of the watered carbid is efiectually prevented and the lamp will thereby remain in a serviceable condition.

The advantages accruing from the herein described construction are important'ones.

and combined to formanextremely useful and efficient acetylene miners lamp.

-What I claim is 2-- A Y 1. In an acetylene lamp the combination of a water reservoir provided with an inlet opening therein, a plurality of carbid container's removably mounted therebeneath and supported thereby, tubes communicating with'the' said reservoir and with the sai containers, means for regulating the water supply through thesaid tubes, gas burner tubes communicating with the said carbid containers and provided with flared ends.
